A lost for words

A few days ago I found I was expecting and that I was 4week's now I am five weeks and find out I'm having a miscarriage I'm so heart broken because my husband and I had been trying to conceive for over 11 month's we have a 6year old son together but we wanted another baby I'm so devastated I'm not understanding how you get great news and then it's taken from you just as fast we had just told our family and friends now we have to tell them we are no longer getting that baby in October we expected I'm so lost for word's
